Modbus Relay Output Module
DAT3138
The Modbus 8 Channel Relay Output Module DAT3138 has 8 Relay outputs. The DAT3138 has 8 single pole double throw relays isolated from each other, the power supply, and the Modbus RTU RS485 input. The contact load is 2 Amps at 250 Vac or 30 Vdc with a 1000 Vac isolation between the contact and 4000 Vac between the contact and the coil.
The LED's on the DAT3138 indicate the power, transmit and receive status, and an indication of the eight relays. The DAT3138 can be configured with the DAT3000-DAT10000 software found on the Datexel Download page.
